Mechanical Tests of 50 Years Old CONRETE with Significant Replacement of Cement with Fly Ash

Experimental analysis of two type of specimens taken from more than 50 years old concrete structure. 28% of cement was replaced with fly ash. Compressive and tensile test were performed.Mechanical tests were performed on samples taken from the dam body. Two kinds of samples were used. One taken from the inside of the dam body and the other, which were obtained from the technological modifications in the crown of the dam. Tests have proven excellent concrete quality. The current strength is significantly higher than the strength he assumed dam proposal. Keywords: Concrete, Fly Ash, Mechanical tests, Compressive strength
